==Aims==
To develop a web based knowledge bank that is accessible to the general public. The knowledge bank will contain independent data, rest results, reports and case studies related to energy storage systems. The goal is to help provide a reliable source of information to the stake holders in the renewable energy storage industry.

----

==Background==
There has been a lot of study done in the area of battery modeling and management systems to help better our understand of and hopefully predict battery performance. But there are a number of different factors that affect the performance of a battery during operation.
For the purpose of this project, in the following figure 1 shows a simple model for a battery. This is the most simplistic battery model showing Resistance Ro, open circuit voltage Uoc and the terminal voltage UL. Ro in this case we are assuming to be purely resistive, can be used to assess the health of the battery. The internal resistance(Ro) of batteries will increase over time as the health of the battery deteriorates. In the case of Valve-Regulated Lead-Acid batteries(VRLA) when the internal resistance is increased to 150% of the original value, the capacity of the battery will be reduced to 80%[2]. Often it is hard to determine the exact parameters of batteries even when data are collected under strictly controlled environments. (temperature, humidity). In this project, we will research and organize useful information and data to produce a knowledge bank.

Methodology
The project includes two parts, one is the website management and the second part is testing system. Researching is the important step at the preliminary stage. During the researching step, the website layout can be designed. And the content for each part can be added after we got the result form the part two. At the beginning of the part two, to decided each component and battery, the circuit should be designed firstly. After setting up the circuit, doing discharging, charging the battery and getting the results. The finial step is accomplishing the website management which is combined with the results which are analysed.

Figure 1 circuit layout connection diagram

In the Above figure shows the hardware setup for the battery testing circuit. The circuit take measurements of battery terminal voltage, current, outer temperature and logs these data onto an SD card. The test circuit is able to run either from a USB or a 9 volt battery. The Low current draw of the circuit allows the testing set up to run for extended period of time on battery sources.

The output current to the load of the battery being tested can be controlled by the on board micro-controller (arduino mega 2560). This is achieved by adjusting the duty cycle of the PWM that feeds into a MOSFET gate. Through coding, we can also adjust the current to control the desired power output. while the test circuit is not yet able to control the temperature, at low discharge current, temperature of our lead-acid battery stayed fairly consistent, so the temperature change can be neglected.
The circuit is designed to discharge current safely up to 5 amps and 100 watts. But higher current and power dissipation is possible with upgraded components.

===Results===

Figure 2 below shows the voltage data taken over time at constant discharge current rates. The sample rate is at 0.3Hz. discharge duration varies from 3 hours to 12 hours depending on the discharge current. The time axis in the below graph is in LOG, while in linear scale, the change of voltage over time displays a linear characteristic during 10%-80% Stage of charge. This shows that we can use the voltage of the battery to give a fair estimation of The remaining state of charge of the battery given that previous performance data are available.

==Conclusion==
Our test set up allows us to collect information such as voltage, current, temperature while implementing control over the circuit.
The Previous figure 2 shows the voltage over time profile of the particular VRLA battery that we tested. The test was done at set constant currents. The voltage over time of a VRLA can be used as a good indication of the SOC of the battery as the relationship of voltage vs time appears to be linear at 10-90% capacity.

----

==Future work==
The test can be performed in a more controlled environment to reduce the effect of the effect of temperature. More data of difference batteries needs to be collected and included in the knowledge bank.

==Conclusion==
Our test set up allows us to collect information such as voltage, current, temperature while implementing control over the circuit.
The Previous figure shows the voltage over time profile of the particular VRLA battery that we tested. The test was done at set constant currents. The voltage over time of a VRLA can be used as a good indication of the SOC of the battery as the relationship of voltage vs time appears to be linear at 10-90% capacity.

----
==Future work==
The test can be performed in a more controlled environment to reduce the effect of the effect of temperature. More data of difference batteries needs to be collected and included in the knowledge bank.

==Aims==
To develop a web based knowledge bank that is accessible to the general public. The knowledge bank will contain independent data, rest results, reports and case studies related to energy storage systems. The goal is to help provide a reliable source of information to the stake holders in the renewable energy storage industry.

----

==Background==
There has been a lot of study done in the area of battery modeling and management systems to help better our understand of and hopefully predict battery performance. But there are a number of different factors that affect the performance of a battery during operation.
For the purpose of this project, in the following figure 1 shows a simple model for a battery. This is the most simplistic battery model showing Resistance Ro, open circuit voltage Uoc and the terminal voltage UL. Ro in this case we are assuming to be purely resistive, can be used to assess the health of the battery. The internal resistance(Ro) of batteries will increase over time as the health of the battery deteriorates. In the case of Valve-Regulated Lead-Acid batteries(VRLA) when the internal resistance is increased to 150% of the original value, the capacity of the battery will be reduced to 80%[2]. Often it is hard to determine the exact parameters of batteries even when data are collected under strictly controlled environments. (temperature, humidity). In this project, we will research and organize useful information and data to produce a knowledge bank.

==Conclusion==
Our test set up allows us to collect information such as voltage, current, temperature while implementing control over the circuit.
The Previous figure shows the voltage over time profile of the particular VRLA battery that we tested. The test was done at set constant currents. The voltage over time of a VRLA can be used as a good indication of the SOC of the battery as the relationship of voltage vs time appears to be linear at 10-90% capacity.

----
==Future work==
The test can be performed in a more controlled environment to reduce the effect of the effect of temperature. More data of difference batteries needs to be collected and included in the knowledge bank.

==Aims==
To develop a web based knowledge bank that is accessible to the general public. The knowledge bank will contain independent data, rest results, reports and case studies related to energy storage systems. The goal is to help provide a reliable source of information to the stake holders in the renewable energy storage industry.

----

==Background==
There has been a lot of study done in the area of battery modeling and management systems to help better our understand of and hopefully predict battery performance. But there are a number of different factors that affect the performance of a battery during operation.
For the purpose of this project, in the following figure 1 shows a simple model for a battery. This is the most simplistic battery model showing Resistance Ro, open circuit voltage Uoc and the terminal voltage UL. Ro in this case we are assuming to be purely resistive, can be used to assess the health of the battery. The internal resistance(Ro) of batteries will increase over time as the health of the battery deteriorates. In the case of Valve-Regulated Lead-Acid batteries(VRLA) when the internal resistance is increased to %150 of the original value, the capacity of the battery will be reduced to %80[2]. Often it is hard to determine the exact parameters of batteries even when data are collected under strictly controlled environments. (temperature, humidity). In this project, we will research and organize useful information and data to produce a knowledge bank.

Methodology
The project includes two parts, one is the website management and the second part is testing system. Researching is the important step at the preliminary stage. During the researching step, the website layout can be designed. And the content for each part can be added after we got the result form the part two. At the beginning of the part two, to decided each component and battery, the circuit should be designed firstly. After setting up the circuit, doing discharging, charging the battery and getting the results. The finial step is accomplishing the website management which is combined with the results which are analysed.

==Aims==
To develop a web based knowledge bank that is accessible to the general public. The knowledge bank will contain independent data, rest results, reports and case studies related to energy storage systems. The goal is to help provide a reliable source of information to the stake holders in the renewable energy storage industry.

----

==Background==
There has been a lot of study done in the area of battery modeling and management systems to help better our understand of and hopefully predict battery performance. But there are a number of different factors that affect the performance of a battery during operation.
For the purpose of this project, in the following figure 1 shows a simple model for a battery. This is the most simplistic battery model showing Resistance Ro, open circuit voltage Uoc and the terminal voltage UL. Ro in this case we are assuming to be purely resistive, can be used to assess the health of the battery. The internal resistance(Ro) of batteries will increase over time as the health of the battery deteriorates. In the case of Valve-Regulated Lead-Acid batteries(VRLA) when the internal resistance is increased to %150 of the original value, the capacity of the battery will be reduced to %80[2]. Often it is hard to determine the exact parameters of batteries even when data are collected under strictly controlled environments. (temperature, humidity). In this project, we will research and organize useful information and data to produce a knowledge bank.

**Inexpensive and simple to manufacture;
**Low cost per watt-hour;
**Low self-discharge;
**Lowest among rechargeable batteries;
**High specific power, capable of high discharge currents;
**Good low and high temperature performance;
*Limitations
**Low specific energy;
**Slow charge, fully charge takes 14-16 hours;
**Limited cycle life, repeated deep-cycling reduces battery life;
**Flooded version requires watering;
**Not environmentally friendly;

==Conclusion==
Our test set up allows us to collect information such as voltage, current, temperature while implementing control over the circuit.
The Previous figure shows the voltage over time profile of the particular VRLA battery that we tested. The test was done at set constant currents. The voltage over time of a VRLA can be used as a good indication of the SOC of the battery as the relationship of voltage vs time appears to be linear at 10-90% capacity.

----
==Future work==
The test can be performed in a more controlled environment to reduce the effect of the effect of temperature. More data of difference batteries needs to be collected and included in the knowledge bank.

1 Project Introduction
This first section of the introduction should clearly state the scope of your project. It should give the reader a broad idea of what the project set out to achieve. A figure such as a system diagram, a photograph, or a flow chart showing how the system is used, can be very effective at this point.
Please note:
1. It is recommended you adapt the structure of this template to suit your project. The structure in this template is more appropriate to a final report than a progress report.
2. Feel free to adjust the formatting of the body of the report but please leave the format of the title page unchanged.
2 Aims
Describe the reasons why the project is interesting or important.
3 Background
Survey other published work on this problem. Explain the relationship between your work and previous work.

4 Hardware overview
Describe the theory underpinning the project if appropriate. Only cover theory that is directly relevant to the project and only if it would be unfamiliar to a typical reader (i.e. one of your classmates).
Renewable energy has been identified as the solution to the world’s ever growing energy problems and demands. With the fast growing market of the Renewable energy sector, there are many new technical challenges that arises from the changes.
One of the major issues with the incorporation of solar or wind into the grid is that it causes unwanted instability [1]. The reason being the energy produced is unpredictable due to weather changes. Thus by implementing energy storage along with the energy sources [2], we can storage energy during peak times and then discharge during low production periods.
